Smicra odontotae (Howard) Cbesson, Synopsis of the families and genera of 

 the Hymenoptera of America north of Mexico, p. 234, 1887. 



This small, dull-yellow species is most easily recognized by its 

 short antennal scape and stout flagellum, with the ring segment 

 one-half the length of segment 4, the shallow scrobe cavity, the head, 

 from the dorsal aspect, being one-half as long as wide, and a strong 

 carina on the genal area of the head, extending from the base of 

 the mandible to the lateral ocellus. 



Description. — Dull yellow with brown markings; all dorsal sutures 

 of thorax, vague mesal stripe near apex of mesopraescutum, broad 

 irregular longitudinal mesal stripe of mesoscutellum, variable areas 

 on pleuron and venter, teeth of metafemur, lateral areas of propo- 

 deum, and transverse bands on abdominal tergites 5 to 8, brown; the 

 head of one female specimen is bright red, but another specimen of 

 the same sex has the head yellow. 



Female : 3.5 mm. Apex of antennal scape not quite attaining level 

 of ventral margin of anterior ocellus, pedicel one-fourth longer than 

 and ring segment one-half length of segment 4, segments 4 to 10 

 equal in length and as wide as long, last three segments slightly 

 shorter; scrobe cavity shallow, interantemial projection with a minute 

 dorsal carina; frons laterad and dorsad of scrobe cavity coarsely 

 punctate, area ventrad of antennal bases provided with a few ir- 

 regular punctures, spaces between punctures minutely reticulated; 

 frontal tentorial pits located near eye margins slightly dorsad of 

 antennal bases; width of malar space one-third height of compound 

 eye; frontogenal suture arced; on gena, a strong carina extends 

 from midpoint of base of mandible around posterior margin of com- 

 pound eye to posterior ocellus; combined width of compound eyes 

 equal to width of interocular space at level of antennal bases; left 

 mandible with two acute teeth, right with three; diameter of pos- 

 terior ocellus two-fifths interocellar space. 



Dorsum of thorax covered by shallow, irregular punctures, area 

 at anterior margin of mesopraescutum without punctures, but mi- 

 nutely shagreened; pubescence long, dense, white; anterolateral angles 

 of pronotum minutely carinate, anterior dorsal margin acarinate; 

 parapsidal furrows distinct; prepectus narrow, fingerlike, not quite 

 reaching tegula; mesoscutellum with a narrow apical lamina; met- 

 episternum strongly punctured, pubescence long and dense ; metacoxae 

 minutely shagreened, shallowly pitted and setose on outer ventral 

 side; metafemur rather slender, outer surface minutely reticulated, 

 densely covered by short setae, ventral margin with 16 to 18 small, 

 acute teeth, basal one slightly larger; inner tooth acute. 



Propodeum provided with irregular, strong carinae, areas between 

 carinae almost glabrous, one small lateral projection present at each
